Tried to put our site live on HTTPS but it is showing content that is being loaded over HTTP so wont validate. It looks like it could be from the custom work you guys did for use. Can you let me know where we update this reference to HTTPS please:

was loaded over HTTPS, but requested an insecure stylesheet 'http://OUR-DOMAIN.com/wp-content/uploads/noo-emigo/custom.css'. This request has been blocked; the content must be served over HTTPS.
